PhD position available

We are offering a fully funded PhD position in evolutionary biology, focused on modelling evolutionary processes using shark paleontological and neontological data. The successful candidate will work on the SHARK-XT project, which aims at establishing the factors that predict extinction risk in the past and future.

The deadline is next April.

Our new publication

We analysed the oldest fossil occurrences of all extant sharks and rays and found that while living genera extend 190 Ma,

species can go back in geologic time as far as 66Ma. Interestingly, species currently  threatened with extinction have the oldest records. 



Catalina's career and research highlighted in the Colombian press


The most read newspapers in Colombia, El Tiempo and El Espectador, published a profile of Catalina's career and her research on Megalodon.

We infer †O. megalodon body dimensions based on anatomical measurements of five ecologically and physiologically similar extant lamniforms.  Our results suggest that a 16 m †O. megalodon likely had a head ~ 4.65 m long, a dorsal fin ~ 1.62 m tall and a tail ~ 3.85 m high. Morphometric analyses further suggest that its dorsal and caudal fins were adapted for swift predatory locomotion and long-swimming periods.

Shark Week? We have the facts

Jack wrote a series of articles on the Bristol Dinosaur Project Blog about all we know about Megalodon. These aim to provide accurate information on the species during The Discovery Channel's Shark Week.
